OIL-BURNER. s

SPECIFICATION forming part of Lettersrlatent No. 779,029, dated-January 3, 1905.

Application filed April 4, 1904. Serial No. 201,405. I

To all whom t may concern:

Beitknown that we, Ross B. DE REMER and JOSEPH B. ROBINSON, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and'State of California, have invented a new and useful Oil-Burner,of which the following is a specification.

' This invention relates particularly to oilburners designed for use in stoves, particu- One object of the invention is to provide a.

burner which is simple in construction and which will produce, with a proper mixture pf air and gas, perfect combustion, with no v smoke and with aminimunn amount of distillate.

Another object is to provide means for effectively cleaning the burner without removing any of the parts of the stove or burner and without using a scraper or other tool, the entire burner, together with the cleaning device, being self-contained.

Another object is to so arrange the burner in the fire-box of the stove and so construct the parts of the burner, which are embodied to an extent in the structure of the lire-box, as to limit the introduction of air to the fire-box to a definite point, so located with respect to the burneras to supply oxygen to the Hanne from the burner at the most eective point of the flame and promote combustion to the highest degree.

Other objects of the invention will appear fromthe following description.

The accompanying drawings illustrate the invention.

Referring to the drawings, Figure 1 is a sectional view taken vertically through a stove longitudinally of the fire-box looking from the rear of the stove toward the front, showing the burner in place, the burner being shown in elevation. Fig. 2 is a sectional view on line X2 X2, Fig. 1. Fig. 3 is a perspective of the liningplate. Fig. 4-is a sectional View through the burner, enlarged and removed from the lirebox. Fig. 5 is a detail view of a portion of the shank of the double-threaded cleaning-pin.

1 designates the body of the stove, having the fire-box 3, which is provided with the usual lining of refractory material 4.

5 is the top of the stove, having lids 6. The bottom of the fire-box and front of the fireboX are lined by a plate 7, formed, preferably, of a single piece of sheet metal, the vertical leaf of which has an air-slot 8 and the bottom leaf of which has an orifice 9.

The edges of the lining-plate 7 closely fit with the lining fof refractory material 4, so that the fire-box is substantially air-tight, air only being permitted to enter at the slot 8. Air is admitted through the orifice 9 to the burner proper, which comprises a head 10, consisting of a hollow cylindrical ring 11, having a central web 12. The upper wall of the head is provided with jet-orifices 13, suitably spaced. A thimble 14 is screwed to the head 10 and communicates with the interior thereof, and screwed to the thimble 14 is a T 15, the lower leg of which closely fits the bottom leaf of the lining-plate 7, projecting through the orifice 9. Screwed to the T 15 is a gas-nozzle 16, having a relatively small gas-passage 17 extending rearward Afrom its point and' communicating with a larger chamber 18, in the walls of, which are formed a conical shoulder 19 and an abrupt preferably square shoulder 20.

A cleaning-pin 21, which is of a size to closely fit the gas-passage 17 and which is adapted to be pushed into and through the gas-passage 17,

`is carried on the end of a shank 22, which traverses the chamber 18 and is provided with a conical shoulder 23 and an abrupt preferably square shoulder 24, which shoulders are respectively adapted to abut against the shoulders 19 and 20, before mentioned. At the rear of the shoulder 24 the shank 22 is enlarged in diameter and is screw-threaded, having, preferably, a double thread, which is received by the rear portion of the gas-nozzle 16.

A hand-wheel 25 is provided on the end of the shank 22 for screwing the shank forward or backward to force the cleaning-pin 21 into and out of the gas-passage 17 to clean the same. A packing, preferably of asbestos 26, is provided around the shank 22 to prevent the escape of gas, being confined in place by suitable stuffing-box 27.

A tubular retort, comprising a cylindrical member 28, is arranged above the head 10. One end of the retort communicates, through a relatively small pipe 29, with the chamber 18 of the gas-nozzle, while the other end of the retort communicates by a pipe 30 with a needle-valve 31 for regulating the supply of distillate or other fuel tothe retort.

32 is a pipe for conveying the supply of fuel to the needle-Valve. A specific construction of the needle-valve 31 is immaterial to lthe present invention. Any good form of needlevalve is well adapted for the purpose, and as the needle-valve per s@ forms no part of the present invention and as needle-valves are well known in the art it is not necessary to describe the needle-valve in detail.

Referring to Fig. 1, it will be seen that the burner just described is arranged within the lire-box 3 in such a manner that the retort 28 lies between the top of the stove and the burner-head and that the shank of the gasnozzle 16 extends through the end of the lire-box, as shown, so that the hand-wheel 24 is vwithin convenient reach. The pipe 30 also extends through the other end of the lire-box, leaving the needle-valve 31 in a convenient position for regulating the supply of fuel to the burner. It will also be noticed that the air-slot 8 is so arranged that it is about on a line with the upper rim of the burner-head 10, so that air entering in a sheet throughl the slot mixes with the flame issuing from the orifices 13.

In operation the needle-valve 31 is opened to permit oil to flow into the retort 28 and is first heated by means of waste or kindling until sufficient gas has been formed to start the burner. It will be noticed that' the pipe 29 communicates with the retort 28 at the highest point of the retort. This prevents any oil which may not have been formed into gas from running down from the pipe 29. As soon as gas has been formed it passes through the pipe 29 into the gas-nozzle 16 and issues with considerable velocity through the passage 17. As it issues from the passage 17 it mixes with air which enters through the lower leg of the T 15, the air being sucked in through the T by the issuing jet of vapor in a manner similar to the action of an injector. The mixture of gas and air then passes into the head 10, from whence it issues through the orifices 13 and ming'les with the air which enters the firebox through the slot 8, andA the flames from the burner-head serve to form the distillate in the retort into a gas, this action being continuous after the burner has been started.

The small passage 17 may readily be cleaned at any time by screwing in the cleaning-pin 21, the blunt end of which forces out any solids which may have collected in the orifice.

While We have shown and described the preferred construction of our invention, it should be understood that yvarious changes may be made therein without departing from the spirit of the invention.

What we claim is- 1. A lire-box, a lining therefor comprising a single piece of sheet metal the vertical leaf of which has an elongated horizontally-arranged slot, the bottom leaf having an air-orilice, a burner-head within the lire-box having its upper rim about in line with the slot, aretort above the burner-head, means for supplying oil to the retort, and means fork conveying gas from the retort to the burnerhead.
